Key result
Radial long axis SSFP cine MRI accurately measured left ventricular volumes, correlating well with short axis TGE and SSFP volumes (r > 0.98) with excellent interobserver agreement (variability < 2.3%).

Does radial long axis SSFP cine MRI accurately measure left ventricular volumes and mass compared to short axis sequences?
Effect estimate: r > 0.98
Radial long axis SSFP cine MRI is a fast, accurate method for obtaining left ventricular volumetric data with excellent interobserver agreement and correlation with short axis sequences.
Bloomer et al. (2001) conducted an observational in Left ventricular volume and mass measurement. Steady state free precession (SSFP) cine sequence in radial long axis orientation vs. Short axis turbo gradient-echo (TGE) and SSFP sequences was evaluated on Correlation of measured left ventricular volumes and interobserver agreement (r > 0.98). Radial long axis SSFP cine MRI accurately measured left ventricular volumes, correlating well with short axis TGE and SSFP volumes (r > 0.98) with excellent interobserver agreement (variability < 2.3%).
